Huntleigh Sonicaid Digital SR3 – Fetal Doppler 3MHz

Accurate, clear, and advanced fetal heart rate monitoring with digital precision for confident prenatal care.

Product Overview

The Sonicaid SR3 Digital Doppler is a high-performance handheld fetal Doppler designed to deliver accurate fetal heart rate (FHR) detection with enhanced visual and audio feedback. Ideal for midwives, GP practices, and obstetric care settings, the SR3 combines advanced digital technology with ease of use for reliable monitoring throughout pregnancy.

Featuring a high-sensitivity 3MHz waterproof probe, the SR3 is particularly effective for early gestation while also supporting general screening across all stages of pregnancy. Its high-resolution colour display shows both large numeric FHR values and real-time waveform traces, providing clinicians with greater diagnostic confidence.

With integrated data storage, USB connectivity, and dynamic digital noise reduction, the SR3 enhances both workflow efficiency and signal clarity. Designed for portability and durability, it is suitable for use in clinics, hospitals, and community environments.
